Open Stack

Hi, maishsk


I have deployed serveral test environment in my company's labs and each environment has 20-30 servers.


Here were the problems I have met.


1. MongoDB consumes too much memory. I use cgroups to restrict the memory used. but if using hard restriction, MongoDB may be terminated by OOM.‍
2. Billing data and monitoring data share the same table and database. This is very inconvenient! Monitoring data is massive and there is no need to backup‍
 monitoring data. On the contrary, billing data is less and important which should be backuped. Mixing these two data together makes things becomes difficult.
3. It posed too much pressure on MQ when we configured monitoring period into 2-5 seconds. So we configured the pipeline using UDP channel.


Next month we will build a openstack environment about 100-150 servers. I will record my configuration, performance data and problems and I am willing to sharethese data and experience in the near future.

Subject:  [openstack-dev] [Ceilometer] Real world experience with Ceilometerdeployments - Feedback requested



Is Ceilometer ready for prime time?

I would be interested in hearing from people who have deployed OpenStack 
clouds with Ceilometer, and their experience. Some of the topics I am 
looking for feedback on are:

- Database Size
- MongoDB management, Sharding, replica sets etc.
- Replication strategies
- Database backup/restore
- Overall useability
- Gripes, pains and problems (things to look out for)
- Possible replacements for Ceilometer that you have used instead


If you are willing to share - I am sure it will be beneficial to the 
whole community.

Thanks in Advance


With best regards,
